Neptune Cloud Tank

I wasn't getting the look of Neptune with previous experiments that I felt was true to the visualization. I felt the photos were looking too dense and was very reminiscent of the Jupiter series. So I decided to copy an old hollywood visual fx known as the cloud tank. Descriptions on the process and history of it can be found off of these links:

Basic process was to create a layer of salt and fresh water, and use evaporated milk to create the clouds. the densities kept the milk in the middle, and I bounced light around the tank using white boards and blue gels. Special thanks to Jared Wright for helping me with this process.
